  Acid-catalyzed aldol-Meerwein–Ponndorf–Verley-etherification reactions—access to defined configured quaternary stereogenic centers

  摘要：

  A novel asymmetric aldol-reduction-etherification process of aliphatic enolizable aldehydes is described. The intermediately formed aldol adducts-beta-hydroxyaldehydes-were reduced and transformed into the corresponding 1,3-diol ethers by external secondary alcohols at the same time. Thus, with the help of chiral secondary alcohols an access to optically active 1,3-diol ether is given. Furthermore, asymmetric cross-aldol-Meerwein-Ponndorf reactions of enolizable aldehydes can also be realized under these reaction conditions. Crown Copyright (C) 2011 Published by Elsevier Ltd.

• Antimony(<scp>v</scp>) cations for the selective catalytic transformation of aldehydes into symmetric ethers, α,β-unsaturated aldehydes, and 1,3,5-trioxanes

  acidity of [2][OTf] was exploited in the catalytic reductive coupling of a variety of aldehydes into symmetric ethers of type L in good to excellent yields under mild conditions using Et3SiH as the reductant. Additionally, [2][OTf] was found to selectively catalyze the Aldol condensation reaction to afford α-β unsaturated aldehydes (M) when aldehydes with 2 α-hydrogen atoms were used. Finally, [2][OTf]

• Stereoselective one-pot synthesis of highly differently substituted thiochromans
  作者：Andrea Seifert、Rainer Mahrwald

  DOI：10.1016/j.tetlet.2009.09.009

  日期：2009.11

  A highly stereoselective one-pot procedure to anti-configured thiochromans is described. This reaction functions at room temperature in the presence of catalytic amounts of trifluoroacetic acid. The transformation gives a selective but optional access to highly substituted thiochromans, which have been not attainable until now.

• A High Yield Procedure for the Me3SiNTf2-Induced Carbon-Carbon Bond-Forming Reactions of Silyl Nucleophiles with Carbonyl Compounds: The Importance of Addition Order and Solvent Effects
  作者：Kazuaki Ishihara、Yukihiro Hiraiwa、Hisashi Yamamoto

  DOI：10.1055/s-2001-18761

  日期：——

  We demonstrate the efficiency of Me3SiNTf2 (0.3-1.0 mol%) as a strong Lewis acid catalyst for the Mukaiyama aldol and Sakurai-Hosomi allylation reactions, and that the slow addition of carbonyl compounds to a solution of acid catalyst and Me3Si-Nu is very important for suppressing side products; this may be widely accepted as a common and reasonable general procedure for the Lewis acid-induced reaction of Me3Si-Nu with carbonyl compounds.

  我们证明了 Me3SiNTf2 (0.3-1.0 mol%) 作为 Mukaiyama 醇醛和 Sakurai-Hosomi 烯丙基化反应的强路易斯酸催化剂的效率，并且将羰基化合物缓慢添加到酸催化剂和 Me3Si-Nu 的溶液中非常有效。对于抑制副产物很重要；这可能被广泛认为是 Me3Si-Nu 与羰基化合物路易斯酸诱导反应的常见且合理的通用程序。
